Nerve pain is created within the nervous system, a complex network of nerves and cells that carry messages between the brain and spinal cord and your body. It is through this system that we feel, move and control our bodily functions.
Nerve roots leave the spinal cord via the intervertebral foramina (holes or spaces between the vertebrae) and join together from various levels of the spine to travel as cord-like structures, called nerves, to their destinations.
It is these nerves that travel outside the spinal cord that are referred to as “peripheral nerves”. Some peripheral nerves travel only a short distance and others all the way from the lower back to the foot. Along their journey they run between and through muscles and fibrous tunnels.
While “radicular pain” arises from a problem as the nerve root exits the spine, nerve-related pain may develop due to a problem along the pathway of a peripheral nerve, outside the spine. Pain related to a nerve is called “Neuralgia”.
